Why Switch from Censys?
Censys is a solid domain API provider, but it's not the only option. Whether you're looking for better pricing, more features, or simply want to explore what else is available - you've come to the right place.
We compare the key differences between Censys and its alternatives. DomScan is one option for teams that value a recurring free tier, a broad toolkit, and remote MCP access.
Common Reasons to Switch
- Need domain-focused API, not infrastructure scanning
- Want simpler pricing without enterprise contracts
- Looking for WHOIS and domain availability
- Building domain tools rather than security scanners
Who Should Stay with Censys
Censys excels at internet-wide scanning and certificate transparency. For security research and exposure management, it remains unmatched.
